the sun reflects in a straight beam on the water. Moonlight reflects in a V shape.

Sorry could you run that past me again.
I don't understand.

I was studying light reflections on the ocean -- sun viz moon for some paintings. Sunlight goes in a straight beam across the water (as in the snaps above) but moonlight narrows to a V-point. (Beggar, it was 12 years ago, maybe I have it backwards -- inverted V?) Buadhai has the ref right. Check it out next your at a moonlit night by a river or ocean. Must be going daft; I studied those patterns for so long and then painted some abstract flowers.
